Using Computer Proof-Assistants in History of Philosophy

Proof-assistant programs are interactive programs. They can be used to assert claims and create formal proofs and, as users input data into a proof-assistant, they can give hints about how to prove the desired claim and machine-check the user’s input. In these respects, proof-assistant programs act rather like a human tutor would: they guide and check a user’s work. Proof-assistant programs have been applied in reconstructing philosophical arguments, but never to history of philosophy. This project will be the first to do so. Proof-assistants will be applied to Principia Mathematica, a landmark work in 20th-century philosophy and logic. Experts disagree over how to interpret Principia. For example, the proofs are often schematic in Principia: not every step is explicitly carried out. Proof-assistant programs will be used to fill in the missing steps and to machine-check that the suggested completions are correct. Additionally, Principia will be computer-checked under different experts’ interpretations. This will in effect empirically test the various interpretations of Principia: one interpretation may leave more gaps in machine-checked proofs than alternatives, counting against that reading. This project will even produce machine-readable data regarding these different readings of Principia, enabling visualizations of this monumental 2,000-page work for the first time.
